ASA H. ALLISON OF NEAR COLUMBUS, INDIANA, ASSIGNOR OF ONE-HALF TO JOSEPH I. IRWIN, OF SAME PLACE.

FENCE-MACHINE.

SPECIFICATION forming part of Letters Patent N0. 349,294, dated September 21, 1886.- Application filed July 10, 1886. Serial No. 207,633. (No model.)

To all whom it may concern.-

Be it known that I, AsA H. ALLISON, a citizen of the United States, residing near Columbus, in the county of Bartholomew and State of Indiana, have invented a new and useful Improvement in Fence-Machines, of which the following is a specification.

My invention relates to an improved device for twisting the wires together in weaving slatwire fences.

The object of my improvement is to provide, in a simple and cheap device for twisting the wires together, means for automatically elamping the device to the wires, and thereby causing the shortening of the wires as they are twisted together to operate to force the slat to its place, all as hereinafter fully explained.

The accompanying drawings illustrate my invention.

Figure 1 represents a front elevation; Fig. 2, an elevation showing one side; Fig. 3, an elevation showing the opposite side; Fig. 4, a transverse section at a, Fig. 1. Fig. 5 illustrates the manner of building a fence with 2 5 my device. I

The body of my machine eonsistsof a twohandled bar, I), having a central hub or boss,

0. The opposite edges of said bar are slotted transversely, as at (l, to receive the fence wires cf. Said slots are enlarged intcriorly, as shown in dotted lines in.Figs. 2 and 3, so that the wires cannot be drawn against the interiors of the slots during the process of twisting them.

h is a thin metallic plate, having on opposite sides of the center radial slots 13 and j, and having'formed integral therewith a pair of bent arms, k k, which are fastened to the bar, the arrangement being such that a space is left between the plate and bar. A shaft, I, passes loosely through the center of bar I), so as to turn therein, and has also a bearing in the plate h.

Secured'rigidly to opposite endsof shaft Z, so as to turn therewith, are a pair of thin metallic disks, m and n. Said disks are each provided with radial slots 0 1;,corresponding to the slots i and j in plate h.

Projecting from the back side of bar I) is a staple, 0', having its outer edge inclined from the center each way, as seen in Fig. 4. The purpose of said staple is to rest against the edge of the slat to determine the position of the machine in relation to the slat before commencing to twist the wires, and to push the slat forcibly into the bight of the wire previously formed as the twisting of the wires draws the machine toward the slat.

The operation of my machine is as follows:' The several pairs of wires between which the slats are to be embraced having been'secured at one end to the first fence-post, and at their other ends to a distant post or tension device, one of my machines is placed on each pair of wires, shaft I being turned so that the slots in disks m and a register with those in the bar and plate 71, and the wires passing one on each side of the bar and rest ing in the slots. A slat is now placed in position between the wires, and the machine on each pair of wires is pushed forward until. the staple 0' comes in close contact with the edge of the slat. The wires are now twisted together over the edge of the slat by turning bar I) on its center. At the first movement of 7 5 the barit matters not in which direction itis turned-plate h and disks in, and n have a tendency to move in opposite directions, plate 71 moving rigidly with the bar, while the disks, having no rigid connection with the bar, are 8o controlled by the wires, the result being that the wires are cramped and slightly bent be tween the opposite sides of the slots in disk n and plate h, thus preventing the machine from sliding on the wire. As the wires are twisted 8 5 they are shortened, and the machine is thus drawn forcibly against the slat, forcing it closely into the bight of wire previously formed. When the movement of the bar ceases,

a slight movement in the opposite direct-ion o releases the grip on the wire and the machine is slipped along on the wires, and another slat placed in position.

I claim as my invention- 1. Bar 1), plate h, shaft Z, and disks m and 5 n, all combined and arranged to cooperate with each other, as and for the purpose set forth.

2. Bar 1), plate 71/, shaft 1, disks or and n, and

staple r, all combined and arranged to coopr00 crate with each other, as and for the purpose set forth.
